Foreword
This technical document concerns the Data Centers (Internet Data Centers
(IDC), Enterprise Data Center (EDC), the Switches, the Points of Presence
(POPs), that are connected to Internet to a varying degree. The principles
described in this document can also be applied to telecommunication
Centers, credit cards, digital video, to name but a few applications.
1.1 General
Since the emergence of “open” networks, data transmission and
processing has assumed and will continue to assume an increasingly
dominant position in modern economy.
The need to communicate and transmit large data volumes at ever greater
speed (text, data, voice, image, video, etc.) has created a communication
network market, the “network of networks” of which is Internet.
Internet: an international communication network
Internet has become the international standard allowing access to an
enormous amount of information from a simple telephone line.
Development of this network has resulted in major investment in
infrastructures to allow an increasingly greater number of “web surfers” to
connect up to the network in the best possible conditions.
Service providers (SP) are pitched at a variety of levels, from simple
renting of surface and resources to total management of corporate
applications (information management).
Existing networks
Networks under construction
Networks in preparation
Internet is defined as a set of networks interconnected via the TCP/IP
protocol (Transmission Control Protocol/Internet Protocol).
How Internet has developed
In 2001, Internet is fully set up in the USA, still under construction in
Europe and just emerging in Asia.
However, in 2000 the American government launched the NGI project (for
“New Generation Internet”). The aim is to create a “Terabit” infrastructure
that is 1000 times faster than the current Internet, thus proving that Internet
still has a very promising future to look forward to.
2
1.2 How Internet works
The system owes its originality to the absence of a central point. The
network runs on a purely co-operative mode with a multitude of computers
and LANs all with the same prerogatives.
Transmission rate is 1 to 10 Gbit/s.
The information sent by the original host is divided into small packets. Each
packet is sent to the network and takes the quickest route possible at that
particular time. These packets may therefore take very different routes.
They are then received and put back into the right order by the receiving
unit.

Intercontinental networks are normally created by fibre optic links routed
under the ocean (e.g. between New York and London), but can also be
created by means of satellites. Continental loops (backbone) are
connected to the ends of the transcontinental links. A number of loops, that
can be regional or local, then stem off from these backbones.
These networks, which ensure high speed communication, are equipped
with signal regenerators (shelter or cabin) every 60 to 100 km. To finish,
end user connection is ensured by POPs (points of presence) which
provide the interface between the high speed network and the telephone
network (or “lower speed” network).

2.1 Data Centers
A Data Center is a sort of hotel in which all the functions and services
proposed are highly advanced technologies, permanently guaranteeing
users (Internet Service Providers, Application Services Providers, Telecom,
etc.) entire satisfaction in terms of security, dependability and reliability
7 days a week, 24 hours a day
Surface may vary considerably from one site to another, from 250 m2 to
more than 50000 m2, with, on average, surfaces of 3000 m2 in Europe,
3300 m2 in the USA and 1400 m2 in Asia.
Installed power is approximately 1.5 KVA/m2, excluding back up devices,
and looks all set to double within the next ten years.
The global power required to supply these buildings is thus very great.
Services associated with Internet Data Centers:
i Internet Service Provider (ISP)
An ISP offers Internet access for other companies (example in the USA:
BELL South, MIND SPRING).
i Application Service Providers (ASP)
An ASP is a company specialised in management and maintenance of
computer applications on behalf of its customers.
(e.g. Cap Gémini, IBM Global Service or WorldCom with more than 85
sites in 2001).
2.2 Switches
Main switching and regeneration site.
Surface of up to 1500 m2, installed power approximately 1.5 mVA.
2.3 Points of Presence (POPs)
Site for connection to the user or to a LAN.
Surface up to 200 m2, installed power approximately 150 kVA
2.4 Shelters or cabins
Small site for regeneration of the optical network signal. A shelter is
required every 60 to 100 km maximum.

3 - Data Centers
3.1 Cutting edge technology
Information technology and telecommunications are quickly growing
industrial sectors.
Servers, whose processing capacities must be permanently adapted to the
new information flows, are regularly renewed. Server rooms are very
familiar with constant change.
As applications are becoming increasingly critical and costs in event of
failure increasingly higher, required operating uptime is now little short of
100%.
In order to stay at the highest level, Data
Centers are permanently adapting to new
requirements. Equipment and their
associated arrangements are constantly
being updated.
3.2 Data Center figures (for 2001)
On average, in 2001, an Internet Data Center has more than 800 secured
servers in continual operation 24 hours a day, 365 days a year. They have
a storage capacity of more than 38 terabytes (38 million Mb) continually
increasing according to requirements. Each month, 110 terabytes of data
are consulted or exchanged, with a monthly growth rate in the region of 20%.
There are also:
i More than 1 500 000 user domains.
i Over 1 billion pages consulted each month.
i Nearly 2 million POP accounts, and as many e-mails sent each day.
i A level of operating security of nearly 100%.
To avoid slowing down data and to guarantee access during data transfer,
these centres are connected by several independent network firms
(Carriers) to the World Wide Web. Interruption of one of these networks
does not affect data flow.
To guarantee the required operating dependability, data Centers are
equipped with a certain number of utilities:
i an air conditioning system
i a secured electrical distribution system
i an access control system,
i a fire detection system,
i a Building Management system...
5
3.3 Requirements
3.3.1 Continuity of supply
Continuity of supply is essential. Two levels of basic requirements can be
identified, namely:
i High Quality power supply of servers.
i Air conditioning (Heading Ventilation Air Conditioning) of Telecom
equipment and servers.
To provide the necessary operating dependability, production as a whole
(emergency generator, UPS, etc.), electrical distribution (MV, LV, AC, DC
current) and the other utilities (HVAC, etc.) of a data Center must be
designed on the basis of a global dependability study taking into account
the notions of reliability, availability and maintainability.

3.3.2 Flexibility of design
It must be possible to install racks of servers step by step without disrupting
operation of the servers already installed.
As applications are continually being developed, servers can be changed
every 6 to 12 months. Here too, it must be possible to reconfigure the
installation without operating downtime.
6
3.3.3 Diagnosis information feedback
Continuity of supply and flexibility of design of applications require a large
amount of information (data) to be retrieved and fed back to a Building
Technical Management System Center, in order to identify the location of
the failure and ensure prompt maintenance.
For instance:
Monitoring current absorbed by the servers (load monitoring via Prisma
Power to Rack faults) allows feedback of information such as the state or
possible tripping of power circuit-breakers.
3.3.4 Final distribution requirements
Each server consumes roughly 300 VA (for 2002). If we consider 6 to 10
servers per rack, consumption of each bay approaches 10 A. The server
supply is thus protected by a Multi9 C60 type circuit-breaker, installed
either:
i In a switchboard (Prisma Power to Rack) including the main breakers
and current measurement allowing diagnosis and feedback of
information to the Building Technical Management Center.
i Via distribution by busbar trunking: each tap-off is equipped with a circuitbreaker and 3 sockets (1 per phase) according to the local standard for
rack power supply.
3.3.5 Harmonics control
Note:
The maximum theoretical current obtained at 100% of
switch mode power supply load, with a standard harmonic
distortion of 60%, is 173% of nominal value.
For this reason, many specifications require a 200%
neutral oversizing to guarantee protection against these
overloads.
Use of non-linear loads in the server racks causes harmonics to occur
which generate higher than nominal current in the neutral conductor.
As a matter of fact, the connected computers are equipped with switch
mode power supplies. This type of power supply generates considerable
harmonic currents (particularly 3rd harmonic) which add up to a neutral
current.
Some technical considerations
Schneider Electric’s experience in the USA as presented in the “Power
Systems Engineering Data” document (Neutral Currents in Three phase
Wye Systems October 1995, published by Square D Oshkosh, Wisconsin)
shows that:
Applications with currents ≥ 200 A.
Even though theoretical levels of 113% to 130% maximum neutral
current are possible, there is no real site measurement exceeding 100%
neutral current (In practice, standard circuit load is 50% of maximum
current).
Applications with currents < 200A
These applications are the most likely to have higher than nominal neutral
current values. The maximum theoretical value is 173% of neutral current
(√3 In).
A variety of processing methods will have to be used and combined
according to the electrical installation:
i Neutral conductor oversizing (cannot reduce harmonic currents, but
allows them to be considered between the loads and the correction
point).
i Use of filters (active/passive or hybrid)
i Use of isolation transformers,
i Etc.

architecture
4.1 General
Although there is no standard layout, a general architecture can
nevertheless be identified. In most cases, a medium voltage stage for main
and emergency power supply distribution is present, as well as a low
voltage stage including the main LV switchboards (server power supplies,
cold production, building safety, general services, etc.), plus a “High quality
platform” stage providing very high quality and reliable power supply to
servers.
4.2 Electrical distribution stages
4.2.1 Medium voltage distribution
This is the connection to the electrical utility.
It can be redundant with 2 or even 3 incoming lines.
Varying considerably according to the country and the installed power, this
part mainly consists of MV cubicles and MV/LV transformers. In large data
Centers, emergency generators are connected to the MV network via a
transformer/adapter.
4.2.2 Low voltage distribution
This part of the installation greatly depends on engineering principles and
habits.
It includes a cascade of LV switchboards from the main LV board to final
distribution towards all the building utilities (air conditioning, lighting, etc.) A
main LV switchboard is dedicated to building safety (fire detection and
protection, video surveillance, break-in alarm, emergency lighting, etc.).
4.2.3 “High quality platform”
This part consists of a consistent assembly with an insulating transformer,
a main LV switchboard, UPS systems, Main/Standby bypasses and
subdistribution boards designed to supply data server groups.
According to the data Center type, these platforms are repeated and also
backed up by an emergency platform.
